BILER-WATER PURIFIER.

SPECIFICATION forming part Of Letters :Patent N0. 294,754, dated March11, 1884. A Application ined Aprno, Issa. (No moda.)

coupling-rod is inserted, and operates as a binder to hold the said pansin their proper place, and other things more fully explained in anotherconnection.

The object of my improvement is to provide a device for separating andsecreting the lime and sediment from the water to be used in the boilerto which my device is applied, whereby such lime and sediment areprevented from being precipitated upon the inner surface of the boiler.I attain these objects by the mechanism-illustrated in the accompanyingdrawings, in which- Figure l is a vertical section of the entireapparatus. Fig. 2 is a top view of one of the open pans separated fromthe others, which separation is easily accomplished after taking oft'the cover. Fig. 3 is a perspective view of the said shaft orcoupling-rod. Fig. 4 is a vertical section of Vmy device in the boiler,showing among other things the holes 4in the .bottom of the several panscommunicating between the pans, arranged alternately on the respectivesides of the connecting-shaft.

Similar letters refer to similar parts throughout the several views.

The jacket d constitutes the outer framework-of the apparatus, andoperates as a shield to the inner work. The said tubular shaft o is usedas a blow-off pipe. The upper end thereof is closed with a screw-cap, e,which cap retains the top plate, f. The lower end of the said shaft c isfurnished with an elbowcoupling, s, to which may be added other piecesof pipe of any length desired, and arranged at any particular angle, soas to connect with the outsidevof the boiler, and when thus arranged maybe used to blow oft' the said purifier. The water is forced into thepurifier, in the ordinary way, through the pipe i in the top plate, f,and in its course down through the several pans t t it changes fromright to left, and vice versa, according to the l arrangement of theholes 7c 7c in the bottom'of the pans. The bottom pan is perforated withholes p in the rim thereof, through which the puriiied water passes intothe boiler. The said shaft c is also perforated or pierced with holesfrom the chamber of each pan, so that when the outer end of the shaft cbelow the elbow s is opened to the outer air the steam will rush'intothe pans through the openings p, and up through the openings lc into theseveral pans, and out through the shaft c, carrying with it the waterand sediment vin the several pans. It is obvious, therefore, that theboiler is protected from the damaging effect of impure water, as it isthoroughly purified in passing over a heated surface of some twelve orfifteen feet.

The object of the partition n in each pan is to cause the water to passover a larger bottom surface.

It is obvious that I am enabled to blow off and renovate this apparatusfrom time to time as desired without disturbing the water in the boileror stopping the engine. Also, it

V`is obvious that, my apparatus being made in detachable sections, I amenabled to remove them one at a time from the boiler through theman-hole for cleaning or repairing whenever required.

I am aware that prior to my invention boilerwater purifiers have beenused with shelves and pans'and blow-off pipes. I therefore do not claimsuch a combination, broadly; but

Vhat Ido claim as my invention, and desire to secure by Letters Patent,is

l. The combination, in a boiler-water puri- 'eig of a series of pansforming chambers, and

a central column or shaft, c, pierced with holes m m, communicating witheach chamber, all arrangedto operate in the manner and for the purposeherein described.

2. The combination of the inclosing-case d, the series of pans c a,provided with the partition n and holes k lc, and central tubular shaft,c, provided with cap e and the holes m min each succeeding chamber, saidpartition@ being adapted -to cause the water to iiow over the entiresurface of the pans' while iiowing from one to the other, allsubstantially as and for the purpose specified.
